Sounds like an incorrect driver is being loaded. The 27" iMac needs to have the mobile version of the video driver installed.

Try this: Boot to Windows 7 safe mode. You do that by holding down the F8 key on boot up. You'll see a DOS like black and white screen. Select safe mode and press enter. As soon as it boots to safe mode, go to the ATI web site and download the mobile video driver for your ATI card and install it. (Make sure you download the 64 bit driver.) Reboot Windows 7 and you should be OK.

And yes, Windows 7 must be installed to a NTFS drive. No other file system will work.

Let us know if this works. BTW, if you can't use the net from safe mode, you can try downloading the driver from Snow Leopard and then copy it to Windows 7. Boot to safe mode and install.
